AddOns manifest resource

    • Google Workspace add-on manifests define the content and behavior of add-ons and must include all required components.

    • The AddOns top-level configuration includes sections for common settings and configurations for specific Google Workspace host applications like Calendar, Chat, Drive, Gmail, Docs, Sheets, Slides, and Meet.

    • The Common section defines general settings for the add-on that apply across all host applications, including the homepage trigger, layout properties, logo URL, name, allowed outbound link URL prefixes, and universal actions.

    • The LayoutProperties configuration controls the color scheme for the add-on's toolbar and buttons using primary and secondary color settings.

    • A UniversalAction allows defining actions available in the add-on UI that either open a specified URL or run an Apps Script function.
